What is chronic sinusitis?Thursday, August 14th, 2014, 3:17 am
By definition chronic sinusitis or rhinosinusitis is considered when symptoms of nasal congestion, sinus congestion or pressure, sinus headaches, decreased smell with or without yellowish discharge from the nose and/or cough persist for longer than 12 weeks or 3 months. If sinus symptoms last less than 4 weeks that is considered acute sinusitis. For the diagnosis of chronic sinusitis either a nasal endoscopy (endoscope exam of the nose) or a CT scan may be necessary. An empirical trial of antibiotics and steroids, either nasal or oral or both may be considered if CT scan or nasal endoscopy is not available or perhaps expensive. However if symptoms persist despite medication, then either of these two procedures should be performed to confirm the diagnosis. Nasal endoscopy may show evidence of pus or discolored discharge or polyposis or swelling around the sinus openings inside the nose suggesting chronic rhinosinusitis. A CT scan is a more reliable test.
